Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting diode systems require significant effort for mounting and assembly, especially for large-area lighting devices using organic light-emitting diodes, which are less luminous per unit area compared to inorganic sources, making them inefficient for general lighting applications.
Innovation Solution
A self-supporting light panel system with a system carrier that integrates organic light-emitting diodes and drive electronics, allowing for easy handling and mounting as a single unit, featuring a regular grid arrangement and a covering layer for efficient light outcoupling, along with a 'Plug and Play' design for easy integration into existing architectures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If individual organic light-emitting diodes are mounted separately on large areas, then sufficient illuminance is achieved, but mounting effort and assembly complexity increase significantly
Solution Approach 1:
The system is segmented into modular light panels that can be individually handled and mounted, while each panel contains multiple pre-arranged organic light-emitting diodes. This allows the overall large-area lighting to be achieved through assembly of manageable modules rather than individual diode mounting.
Solution Approach 2:
The organic light-emitting diodes are pre-arranged in regular grid patterns on the system carrier before final installation. This preliminary arrangement eliminates the need for precise individual positioning during mounting, significantly reducing assembly complexity while maintaining the required illuminance distribution.
2Reliability
If individual organic light-emitting diodes are electrically connected separately, then functional lighting is achieved, but installation time and complexity increase
Solution Approach 1:
Multiple organic light-emitting diodes are electrically connected to each other and to the system carrier as integrated units before final installation. This merging of electrical connections into pre-assembled modules eliminates time-consuming individual wiring during installation while ensuring reliable functional lighting through tested connections.
3Ease of operation
If organic light-emitting diodes are arranged in a regular grid on the system carrier, then handling as a single unit is enabled, but the system requires a robust mechanical support structure
Solution Approach 1:
The system carrier serves multiple functions simultaneously: it provides the regular grid arrangement for organic light-emitting diodes, acts as a mechanical support structure, enables handling as a single unit, and facilitates electrical connections. This multi-functionality reduces the need for additional separate components.
4Illumination intensity
If a covering layer is added for efficient light outcoupling, then light extraction is improved, but device complexity and manufacturing steps increase
Solution Approach 1:
The covering layer is integrated with the system carrier to form a composite structure that improves light outcoupling efficiency. This composite approach combines the mechanical support function of the carrier with the optical enhancement function of the covering layer in a single manufacturing process, rather than adding separate complex components.

Implementation Method 1
The organic light-emitting diodes in particular each contain at least one organic active layer intended for generating radiation, in which charge carrier recombination takes place
Implementation Method 2
A refractive index of the covering layer differs from a component of the light-emitting diodes which is in contact with the covering layer
